Explanation:

Question 1

Measuring tools in plumbing are used to measure length, height, diameter, levelness (to check if surfaces are level), and plumbness (to check vertical alignment). So all the options A, B, C are correct, hence D.

Layout tools in plumbing are used to produce accurate lines, arcs (or other markings like circles, etc.). A common marking along with lines is arcs for tasks like marking pipe cuts for curved fittings or circular openings.

Common lengths of long steel measuring tapes used in plumbing and construction are 25', 50', 100', 200', and 300' to measure long distances accurately for pipe runs, building layouts etc. So the statement is True.

Answer:

D. All of the above.
